Vultures are used in some cultures to dispose of the dead and it turns out to be far more environmentally friendly than burning precious fire wood, natural gas or polluting rivers or ground water. Then there is the loss of trace element and precious nutrients also associated with western burials deep below the root zone and in containers sometimes that don't break down to return the componets of life for recycling. Obviously you would need a remote location away from communities that might be concerned about the health issues and body parts falling from the sky. Could a fenced off compound with only bird access (no rodents) in the middle of a national park do the trick? Would wedge tailed eagles be up to the task? I read on the net they can sometimes attack live adult kangaroos in groups. Could they get nasty if there was a shortage of bodys and they had aquired a taste for human? Would wedge tailed eagles overcome their territorial instincts and have enough of a collective appetite to devour enough bodies to be a viable dispersal source? With 70% of their diet being rabbits, what impact would this human have? How far would they cart their rabbit size chunks? Who would do the chopping or could it be automated? Do they need lots of trees for roosting and eating? David Suzuki in one of his books talks about rivers flowing backwards, how nutrients from the fish in rivers was somehow ending up high in the forest trees. It turned out to be the eagles carrying the fish and pooing from the trees which then appreciated the trace elements only found in the sea - carried up by the migrating fish. The bears also ate the salmon and crapped on the trees. Could passed on humans be used to fertilise the landscape via birds? By changing much of the landscape with broad monoculture agriculture, how much have we interfered with this refertilisation process, taking away cover and carriers of nutrients from rivers back out inot the upper parts of catchments. Would other Australian birds be able to assist? Kookaburras, Magpies to pick up any scraps left or dropped by the eagles? Some bodies might have to be excluded from the process because of medications - these have had a devastating impact on some birds overseas. You can be buried under trees in some land restoration projects in some parts of Australia but is this the only way to go or might it be better to use a more widely dispersed approach? What would happen to the bones? would bits of bones accumulate under the roosting trees of break down in a composting pile of droppings and biological activity quickly enough? What sort of grave side event would occur to fairwell the departed before they get departed and departed? What sort of memorial would there need to be ? Composted tree burials at least get a GPS location for future reference. How far would people travel as a one way tourist to utilise such a service? How much would these sky burials cost? It appears to be a big business and maybe some of the profits could be ploughed back into funding maintenance and study of the ecosystem. Many of atoms in your body have been through up to three exploding star suns already - what would be so wrong about dispersing through an eagles.
